- 論文の詳細を見る
Alizarin blue combining with zinc formed a colored complex at pH 5.6, and was extracted from aqueous phase by using a mixture of cyclohexanone and ethyl acetate. This complex had a maximum absorption at 635 mμ, the molecular absorption coefficient being 2.69×10^4. After the interference of several cations and anions were examined, microquantities of zinc in tin and lead were successfully determined by this method.
